Substantiating rational schedule to load trucks using draglines while mining a pit of Motronivskyi MPP

Purpose. To substantiate a rational schedule for the combined dragline-truck operation taking into consideration coefficient of mining in context pit. Methodology. Mathematical and graphical modeling was involved while determining concentration pit as well feasibility analysis to select procedure scheme dragline operation. Findings. Recommendations selection operation, truck loading Motronivsko-Annivskyi pit, have been developed degree It has determined that bottom unloading truck, located central part bench width, position at 0.5 A distance from crest, is most efficient plan action conditions. Technological develop proposed. Originality. Dependence upon parameters development system elements according different technological schemes derived. The dependence helps estimate cost overburden rocks using draglines with direct trucks. Practical value. dump developed. Their use makes it possible cut prime activities. Implementation proposed solutions stripping by UAH 79.65 million year if annual volume Qrozkryvu - Qstripping = 13.5 m3/year.
